Prepare the interface of @vitest/ui for translation

Clear and concise description of the problem

The interface of @vitest/ui enables to view and interact with tests. There are few controls and components on the interface, however they seem to be written hard-coded in english, without the possibility to be read in other language, if I am not wrong.

Suggested solution

Proposal 1: @vitest/ui package could provide translations for its UI by default.

Alternative

Proposal 2: @vitest/ui package could at least enable people to provide translations for its UI using the config and/or CLI.

Additional context

Although one person can read english, it may prefer to read in its mother language.
